Question

我在jQuery / HTML中构建简单的“Spot the difference”游戏。有5个回合/阶段，每个都有不同的图片，用户需要从第1轮开始全部完成。

当我在第二轮时，我有两次增量射击这个问题，然后在第三轮时增加三次，等等。这个原因指向跳起双倍/三倍/ ......而不是仅仅跳过1。

代码是婴儿级别的。我没有做任何重构和改进的东西。

我认为我不需要为此提供HTML，因为只需查看JS文件中的逻辑即可。对于那些喜欢pastebin版本的人来说（http://pastebin.com/ACqafZ5G）。完整代码：

(function(){

    var round = 1;
    var points = 0;
    var pointsTotal = 0;

    var pointsDisplay = $(".js-calc");
    var pointsTotalDisplay = $(".js-calc-total");
    var counterDisplay = $(".js-counter");

    var entryPage = $(".entry-page");
    var mainMenu = $(".main-menu");

    var submitNow = $(".js-now");
    var submitResultsFinalBtn = $(".js-submit-results-final");

    // rounds-categories
    var allRounds = $(".round");

    var divRound1 = $(".round1"),
        divRound2 = $(".round2"),
        divRound3 = $(".round3"),
        divRound4 = $(".round4"),
        divRound5 = $(".round5");

    var allPic = $(".js-pic");

    var pic1 = $(".js-pic1"),
        pic2 = $(".js-pic2"),
        pic3 = $(".js-pic3"),
        pic4 = $(".js-pic4"),
        picFinish = $(".js-finish");

        // on the beginning hide all and leave only entry page
        mainMenu.hide();
        allRounds.hide();
        submitResultsFinalBtn.hide();

    // countdown (SEE THE FUNCTION ON THE END)
    var myCounter = new Countdown({
        seconds: 60,  // number of seconds to count down
        onUpdateStatus: function(sec){
            counterDisplay.html(sec); // display seconds in html
        }, // callback for each second
        onCounterEnd: function(){
            console.log('TIME IS OVER!');
            // THIS SHOULD NOT BE HERE, I WOULD PREFER TO MOVE IT SOMEWHERE TO GAME ITSELF
            pointsTotalDisplay.html(pointsTotal);
            round++; // update to next round
            allRounds.hide();  // hide window

        points = 0; // reset the points for this round to 0 - not sure this is the way to do it...

        console.log(points + " points for this round, " + pointsTotal + " in TOTAL"); // say how many points so far

        entryPage.hide();
        mainMenu.hide();

        }

        counterDisplay.html("60"); //display 60sec on the beginning
        myCounter.start(); // and start play time (countdown)
        // pointsDisplay.html(points); // display in HTML amount of points for particular round


        // if user start collecting points, add them

        var mapImage = $('.transparent AREA');

        mapImage.each(function(index) {
            // When clicked, reveal red circle with missing element
            $(this).one("click", function(e) { // YOU CAN CLICK ONLY ONCE!! Using .one() to prevent multiple clicks and eventually scoring more points

    this.stop = function () {
        clearInterval(timer);

Answer 1

你确定你没有将$('.transparent AREA')从一轮转移到另一轮吗？

这可以解释为什么你得分多次：

var mapImage = $('.transparent AREA');

    mapImage.each(function(index) {
        // ...
        points++;
        // ...
    });

Answer 2

解决！

mapImage.each应该在initiateRound之外
